Question No: 4893

Question by: Mr Zhulkarnain Abdul Rahim

To ask the Minister for National Development what are NParks’ plans to ensure that the emergence of non-native species of birds like the red-breasted parakeets in Choa Chu Kang do not adversely affect our native biodiversity and habitats in the long term.

Answer:

The red-breasted parakeet is a non-native species that established a population in Singapore following the release or escape of such birds from captivity. When present in large numbers, non-native species can negatively impact native species through competition for food and nesting sites. They can also increase the chances of transmission of exotic diseases and parasites. 

2        NParks adopts a science- and community-based approach to manage the populations of non-native bird species, so as to minimise their impact on native biodiversity and habitats.

3        For example, to manage the population of red-breasted parakeets in Chua Chu Kang, NParks is working with the Chua Chu Kang Town Council to carry out tree pruning to disrupt the birds’ roosting and nesting sites. NParks undertakes direct population control where necessary, such as by trapping and removing congregations of these birds.

4        NParks also raises awareness on the ecological impact of non-native species through public education and outreach, and takes enforcement action against the illegal release of animals into the wild. Under the Parks and Trees Act, offenders caught releasing an animal in a national park or nature reserve can be fined up to $50,000. Under the Wildlife Act, offenders caught releasing wildlife in any place may be fined up to $5,000.

5        NParks will continue to monitor and carefully manage the populations of non-native species, as well as deter the further introduction of such species into the wild. This will help to safeguard native biodiversity and preserve the resilience of our ecosystem in the long term.
